Westminster: The Sainsbury Wing at the National Gallery (with Purcell)Photographer: Paul Vonberg

For six months, I worked out of a cupboard in the Sainsbury Wing, after Venturi had finished the building but before it was opened by the Queen. My work ranged from refitting the lavatories to designing the barrier rails (seen here) to, best of all, designing the frame and case for the Leonardo Cartoon.
